you can stock those, these are schooling fish and may enjoy larger groups, but thats not etched in stone, i have a single cherry barb in a tank with 3 angelfish thats has been just fine with that arrangement for over a year now.

Personally, I don't think the cherry barbs belong with the others - the tiger barbs (no matter what color they are) are fairly aggressive and potentially nippy where the cherries are more placid and peaceful.

My understanding is the tiger barbs should really be in their own tank or with other aggressive fish. But yes, they do well with a larger group.

Regular, albino, and green tiger barbs are all the same species so it doesn't matter what combination you get them in, they will be fine together. I agree with Imma that the cherry barbs don't really belong in a tank with tiger barbs.
Schooling fish need proper sized schools to feel at home. They may get along fine for a while in smaller numbers, or with just one, but they must have proper numbers to live to their potential and thrive, otherwise we would not call them schooling fish.

When I go fishing I just place a sharp rock in the water and sit there waiting for all the dead fish to float to the top...

Rosy barbs is a better choice to mix with tiger barbs if your tank is big enough.
6 is considered by many to be the minimum, but I think 10-12 is a better minimum, especially with barb species, if your tank has room.
Bronze and peppered cory can be in the same tank, but they are different species so you would need a group of each. Again, if your tank has room.

Corys from different species will occasionally school together in my experience. So if you were to mix Bronze with Peppered you might get a "single school" out of them -- but that also might not happen. I've noticed the Peppered's natural behavior to be slightly different from other Cory species at times, so in my larger tank they only occasionally school with the other Cory. So if I were you and if you don't have the space... I'd just stick with one Cory species so you could get the right amount in there.

Without knowing your tank size and other details it is hard to give more precise information. But I am a huge fan of keeping schooling fish in schools. It reduces stress in a major way when you put them with the "proper" number of fish.

I also agree with mommy1 on the amount of barbs. I know most people say 6 is an adequate school but really anything less than 8 to 10 is a little small -- in my humble opinion that is.

I mixed ruby barbs and tbs once the tbs killed the male rubys when they colored up. Then again they were sold to me as tbs and only 4 in there.

My experience with Black Ruby Barbs and Tiger Barbs was puzzling. Last year I had 7 TBs living in my tank for months when I added 3 BRBs. All my TBs were scared of the BRBs. From what I've read so far, TBs are supposed to be aggressive and BRBs are supposed to be peaceful tank mates. Their sizes were about the same. Now the 2 remaining BRBs are in a separate tank. Haven't decided yet whether I will mix them in my new tank.
